J.Med.Chem., 63:15603-15620, 2020 Cited by PubMed Abstract: Various malignant human diseases show disturbed signaling pathways due to increased activity of proteins within the epigenetic machinery. Recently, various novel inhibitors for epigenetic regulation have been introduced which promise a great therapeutic benefit. Inhibitors for the bromo- and extra-terminal domain (BET) family were of particular interest after inhibitors had shown a strong antiproliferative effect. More recently, the focus has increasingly shifted to bromodomains (BDs) outside the BET family. Based on previously developed inhibitors, we have optimized a small series of 4-acyl pyrroles, which we further analyzed by ITC, X-ray crystallography, selectivity studies, the NCI60 cell-panel, and GI determinations for several cancer cell lines. The inhibitors address both, BET and BRD7/9 BDs, with very high affinity and show a strong antiproliferative effect on various cancer cell lines that could not be observed for BD family selective inhibitors. Furthermore, a synergistic effect on breast cancer (MCF-7) and melanoma (SK-MEL-5) was proven. PubMed: 33275431DOI: 10.1021/acs.jmedchem.0c00478 PDB entries with the same primary citation |
